Bootstrap collapse with dropdown issue - html

I want to the dropdown to be displayed at the bottom of the NAV BRAND (or Nav logo on the top left) when pressing the menu button. But, it appears next to the button in mobile view and in the center. See here:
Below is my HTML code:

I tried to make a login button which opens up a modal for login details. When I click on the button it is referred to that point where I want it to be. But nothing opens up. A similar problem is with another button that has to open up another modal.
My 2nd problem in about the navbar toggling action is not working. there is no response from the button when I click on the toggle button.

There is no Bootstrap JS and jQuery Added, so without it, modal will not work
do not pass href on login button, instead use data-target="#loginModal"
remove FADE class from modal,
I have removed many other classes from your code just for demo purpose, like fixed top on nav, yuou have have those as per your requirements

pull-right in navbar not working

I use Asp.net mvc and bootstrap , I tried to put search bar to the right of the navbar by pull-right and float-right but it's not working seacrh bar stays next to other elements on the left of the navbr.

</div>
</div>
</form>
</div>
</li>
</ul>
</div>
</div>
</div>
The ul has css classes nav and navbar-nav, which gives it the float: left styling, which aligns it with the left of its container, and makes the ul wrap its content without leaving any space between elements unless explicitly instructed to.
In order to see the effects of the float: right on the search bar, try placing that div in the same container as the ul like so:
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>

<div class="navbar-header">

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-2">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
#Html.ActionLink("RAWAN", "Index", "Home")
</div>
<!-- Note the new id: #bs-example-navbar-collapse-2 -->
<div class="navbar-collapse collapse" id="bs-example-navbar-collapse-2">
<ul class="nav navbar-nav" style="color:white">
<li>#Html.ActionLink("News", "About", "Home")</li>
<li>#Html.ActionLink("Supervisors", "Contact", "Home")</li>
<li>#Html.ActionLink("Senior Projects", "Contact", "Home")</li>
<li>#Html.ActionLink("About me", "Contact", "Home")</li>
</ul>
<!-- Search bar -->
<div class=" float-right pull-right">
<form class="navbar-form pull-right" role="search" >
<div class="input-group pull-right">
<input type="text" class="form-control pull-right" placeholder="Search" name="srch-term" id="srch-term">
<div class="input-group-btn">
<button class="btn btn-default pull-right" type="submit"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
You need to place the search bar outside of the <ul> and place it in the same container as the <ul>. Additionally, you only need one pull-right in the top level container for your search bar.

Bootstrap - Navbar won't show on mobile

The button that is used on mobile devices to view the navbar is not showing up when I make the browser window size smaller to see how it looks on mobile. Here is a CodePen to see my code
<div class="container">
<div class="navbar navbar-default navbar-fixed-top">
<div class="container">
<a class="navbar-brand" href="#"><h4>EmulateOS.tk</h4></a>
<div class="collapse navbar-collapse">
<ul class="nav navbar-nav">
<li class="active">Home</li>
<li>Mac OS9</li>
<li>DOS</li>
<li>Windows '95</li>
</ul>
<form class="navbar-form navbar-left" role="search">
<input type="text" class="form-control" placeholder="Search">
<button type="submit" class="btn btn-default"><span class="glyphicon glyphicon-search"></span></button>
</form>
</div>
</div>
</div>
</div>
The nav is supposed to disappear on mobile screens - in mobile views, the menu is visible by activating the menu by clicking a button. The navbar-collapse class ensures this. See the Bootstrap docs for how to achieve this:
http://getbootstrap.com/components/#navbar
And their examples for different ways this can be implemented:
http://getbootstrap.com/getting-started/#examples
Specifically, this is the critical aspect for your code:
<div class="navbar-header">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Brand</a>
</div>
Your code is missing few boot strap styles. Here is the working code -
